On February 11, 2016, the Mosul-based anti-ISIS group Mosul Eye, which documents life in Mosul under ISIS rule, posted a message on its Facebook page in English and Arabic advising Mosul residents to avoid using the communication app Viber, as it stores a user's communication history. The group instead recommended using Telegram. The message reads:
"Warning
"We urge our dear Mosulis to refrain immediately from using Viber as a mean of communication and completely remove it from your devices as it creates an archive of your correspondence and could be easily retrieved. Please refrain immediately from using Viber and never use it under any circumstances for your own safety. We advise you to use Telegram instead because it is secured and does not store any archives of your communication."
